Don’t Take Notes with a Laptop

notetaking“Taking notes by hand requires different types of cognitive processing than taking notes on a laptop, and these different processes have consequences for learning. Writing by hand is slower and more cumbersome than typing, and students cannot possibly write down every word in a lecture. Instead, they listen, digest, and summarize so that they can succinctly capture the essence of the information.”

“Thus, taking notes by hand forces the brain to engage in some heavy “mental lifting,” and these efforts foster comprehension and retention. By contrast, when typing students can easily produce a written record of the lecture without processing its meaning, as faster typing speeds allow students to transcribe a lecture word for word without devoting much thought to the content.”

Garum: Fermented Fish Sauce for the Ancient Roman Masses

Fish fermentation allowed the ancient Romans to store their fish surplus for long periods, in a time when there were no freezers and fishing was bound to fish migratory patterns. [Read more…]

So you want us all to go back to the Stone Age?

The word “back” is a trick. It implies a magical absolute direction of change. Suppose you go to your job, and when you get ready to leave, your boss says, “So you want to go back to your house? Don’t you know you can never go back? You can only go forward, to working for me even more, ha ha ha!” Really, all motion is forward, and forward motion can go in any direction we choose, including to places we’ve been before.

Technology Ages in Reverse

Our society is pathologically enthralled with the new. As scientists and engineers in global development, we’re inculcated starting from very early in our training to seek “the cutting edge” of technological innovation. But if we want the best chance of making a positive difference on the future, that’s the opposite of what we should do.

The reason is that technology ages in reverse. Or put another way, the longer a given technology has been around, the more likely it is to persist into the future. So, if you want your efforts in science to matter in the future, you’d better look to the past to define relevant research questions.

According to philosopher and risk analyst Nassim Taleb, author of Antifragile: Things That Gain from Disorder, while perishable items (such as humans, cats and tomatoes) experience a decline in life expectancy with each passing day, nonperishable things (such as art, literature, ideas and technologies) can experience increased life expectancy the longer they are in circulation. This is known as the Lindy Effect… Taleb asserts that our modern culture trains us to think that the new is always about to overcome the old. But this is just an optical illusion because the failure rate of the new is so much higher than that of the old.
